“…From 1980 to 2014, the main bacterial agents identified in Brazil were Nocardia brasiliensis [15,26,27–32], Nocardia asteroides [15,33], Nocardia caviae [34], Actinomadura madurae [13,35,36], Actinomadura pelletieri [14], and Streptomyces somaliensis [15]. For eumycetoma were Madurella mycetomatis [15,25,37,38], Madurella grisea [39–45], Acremonium falciforme [46], Acremonium kiliense [47], Scedosporium apiospermum [12,18,48,49,50], Fusarium solani [51], Exophiala jeanselmei [44,52,53] and Aspergillus sp. [12].…”

Mycetoma is caused by the subcutaneous inoculation of filamentous fungi or aerobic filamentous bacteria that form grains in the tissue. The purpose of this study is to describe the epidemiologic, clinic, laboratory, and therapeutic characteristics of patients with mycetoma at the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil, between 1991 and 2014. Twenty-one cases of mycetoma were included in the study. There was a predominance of male patients (1.3:1) and the average patient age was 46 years. The majority of the cases were from the Southeast region of Brazil and the feet were the most affected anatomical region (80.95%). Eumycetoma prevailed over actinomycetoma (61.9% and 38.1% respectively). Eumycetoma patients had positive cultures in 8 of 13 cases, with isolation of Scedosporium apiospermum species complex (n = 3), Madurella mycetomatis (n = 2) and Acremonium spp. (n = 1). Two cases presented sterile mycelium and five were negative. Six of 8 actinomycetoma cases had cultures that were identified as Nocardia spp. (n = 3), Nocardia brasiliensis (n = 2), and Nocardia asteroides (n = 1). Imaging tests were performed on all but one patients, and bone destruction was identified in 9 cases (42.68%). All eumycetoma cases were treated with itraconazole monotherapy or combined with fluconazole, terbinafine, or amphotericin B. Actinomycetoma cases were treated with sulfamethoxazole plus trimethoprim or combined with cycles of amikacin sulphate. Surgical procedures were performed in 9 (69.2%) eumycetoma and in 3 (37.5%) actinomycetoma cases, with one amputation case in each group. Clinical cure occurred in 11 cases (7 for eumycetoma and 4 for actinomycetoma), and recurrence was documented in 4 of 21 cases. No deaths were recorded during the study. Despite of the scarcity of mycetoma in our institution the cases presented reflect the wide clinical spectrum and difficulties to take care of this neglected disease.

A young apparently healthy, non-diabetic, HIV non-reactive woman presented with a mycetoma-like lesion on right buttock. Discharge was scanty, and mycotic grains were not seen. Biopsy of sinus track was obtained for microscopy and culture. Microscopic examination revealed plenty of fungal hyphae in direct microscopic examination of grounded tissues in saline; KOH, Gram's, and H and E-stained smears. All the three inoculated slants of Sabouraud's media yielded heavy growth of Fusarium solani. Presence of numerous hyphal fragments in direct microscopy and heavy growth of F. solani in all three slants indicative of etiological role of fungus in the present case. It is probably a first report of F. soloni mycetoma from India.

SUMMARY Fusarium species cause a broad spectrum of infections in humans, including superficial, locally invasive, and disseminated infections. The clinical form of fusariosis depends largely on the immune status of the host and the portal of entry, with superficial and localized disease occurring mostly in immunocompetent patients and invasive and disseminated disease affecting immunocompromised patients. Risk factors for severe fusariosis include prolonged neutropenia and T-cell immunodeficiency, especially in hematopoietic stem cell transplant recipients with severe graft-versus-host disease. The most frequent presentation of disseminated fusariosis is a combination of characteristic cutaneous lesions and positive blood cultures, with or without lung or sinus involvement. The prognosis is poor and is determined largely by degree of immunosuppression and extent of infection, with virtually a 100% death rate among persistently neutropenic patients with disseminated disease. These infections may be clinically suspected on the basis of a constellation of clinical and laboratory findings, which should lead to prompt therapy. Treatment options include the lipid formulations of amphotericin B, voriconazole, and posaconazole. Prevention of fusarial infection among high-risk patients should be considered.
